The specific embodiment

With reference to figure 1, on the broken body such as the breaker of roller mill, vertical rolls milling train, disintegrating machine or grinding mill etc., can form wearing face.For example, broken body can comprise base portion 3a and outer part 3b.Outer part 3b can comprise recess 5, and its size is configured to and is configured to receive card component 7.Preferably, outer part 3b and base portion 3a integrally form, or identical metal body or structure, such as the metal air cylinder structure, part.

The size of card component 7 can be set up and be arranged so that its length of Width of each plug-in unit is long, perhaps can be configured to approximate square shape and maybe can be configured to have different shape and size.Card component is preferably by tungsten carbide and consists of, and it has column, coniform or taper.Plug-in unit can comprise the plug-in unit of difformity and size, and perhaps all plug-in units can be identical shape and size.Card component can be made of other hard material, such as industry diamond processed, diamond or other hard material harder than the material of outer part 3b.

Plug-in unit is preferably harder than outer part 3b and base portion 3a.For example, plug-in unit is preferably harder ball hardness number (Brinellvalue), Rockwell hardness number (Rockwell value), Vickers hardness number (Vickers value), Knoop number (Knoop value) or the Richter scale rebound hardness value (Leeb Rebound value) of hardness number that has than the outer part 3b of broken body or broken body.Such as another embodiment, plug-in unit is preferably has the durometer hardness value harder than the outer part 3b of broken body or broken body (durometer value).

Each plug-in unit 7 can be arranged in the recess 5 that is formed among the outer part 3b.Mortar, cement, adhesive or adhesive such as the high temperature mortar can be used for plug-in unit 7 is positioned in the recess 5, and plug-in unit is bonded to broken body.Should be appreciated that any commerce can be bought, relatively low cost, and adhesive all is preferably spendable relatively reliably.This plug-in unit can be positioned such that whole plug-in unit is arranged in recess or can be configured such that only the part of plug-in unit is arranged in recess.Preferably, plug-in unit is positioned in the recess, so that the outermost portion of plug-in unit is recessed with respect to the outermost portion of outer part 3b.

The second metal structure 9 can be positioned in plug-in unit 7 and broken body top, and is perhaps adjacent with broken body with plug-in unit 7.For example, the second metal structure 9 can be configured such that to have the gap between broken body and the second metal structure 9.The second metal structure 9 can be cladding plate, cover pipe, driver plate, control valve, transmission tube (driver pipe) or other metal structure.Plug-in unit 7 is preferably harder than the second metal structure 9.

Before the described structure in location or before lighting any explosive, can mill outer part 3d and the second metal structure 9.This is milled and can be used for incrustation or other surface blemish surface removal from metal structure.

Preferably, the second metal structure 9 is oriented to plug-in unit 7 adjacent with broken body, so that form the gap between the outer part 3b of the plug-in unit of the second metal structure and embedding and broken body.Can keep the gap by pad being positioned between outer part 3b and the second metal structure.This pad can limit the size in gap.The width in gap can limit and separate size.

One or more explosives can be positioned to adjacent with the second metal structure.For example, the second metal structure 9 can have towards the first side of the outer part 3b of gap and broken body and second side opposite with the first side.It is adjacent with the second side of the second metal structure 9 that described one or more explosive can be oriented to.For example, these one or more explosives can be arranged on the second side of the second metal structure 9 or near the second side of the second metal structure 9.These one or more explosives, for example the explosive material can obtain from supplier or the supplier of described material.

Should be appreciated that these one or more explosives can comprise the explosive material, it comprises any amount of suitable explosive material or the combination of explosive material.For example, should be appreciated that spendable explosive material can comprise ammonium nitrate, amatol, guanidine, nitroglycerine, cyclonite, plastic explosive, explosive powder, ammonium nitrate/fuel oil (ANFO), EL819 type explosive material, T200 type explosive material or other explosive material.

In some embodiments of described method, cover plate or other structure can be arranged on the top of the second metal structure 9 and broken body.The part of described one or more explosives or different explosives can arrange on the cover board, and also contact with the one or more explosives that are arranged near the second metal structure.

Alternatively, the second metal structure and broken body can be arranged such that described the second metal structure cover the first metal structure the top, thereby do not need or otherwise use cover plate.

This explosive can be lighted to impel the second metal structure 9 to contact with the outer part 3b of broken body, thereby thereby makes the outer part 3b distortion of broken body form wearing face plug-in unit is connected to broken body.After the distortion of part 3b is finished outside, the broken body of the second metal structure 9 from wearing face with formation can be removed.For example, can cut the second metal structure, and impact or impact that the second metal structure 9 is separated with broken body or removed from plug-in unit by instrument or machine.Alternatively, can remove broken body from the second metal structure 9, perhaps two structures can be from removing each other.Preferably, after explosive welding, because the distortion of the broken body that the power that one or more explosives of lighting transmit via the second metal structure 9 causes, the part of body covers or centers on so that plug-in unit is broken.

The distortion of outer part 3b also can so that outer part 3b engages with plug-in unit 7, or cause mechanical interlocked plug-in unit is connected to outer part 3b between outer part 3b and the plug-in unit 7.Be appreciated that the example of this distortion that plug-in unit 7 is connected to the outer part 3b of broken body from Figure 1A, 1B and 1C.By lighting being connected of outer part 3b that the caused distortion of explosive material provides plug-in unit and broken body, can be used as the explosive forging (" EXF ") of the outer part 3b of plug-in unit and broken body.

Should be appreciated that, light explosive can between the outer part 3b of plug-in unit 7 and broken body, not set off an explosion the welding or other welding.Between plug-in unit 7 and outer part 3b, can not produce metallurgical binding.

If broken body is cylindrical shape or other structure that comprises therein center-aisle, can before lighting explosive, in passage, fill central plug (central plug).This plug is set supports this structure, and prevent owing to light power that explosive transmits and cause this structural failure or be out of shape in the mode of not expecting.Lighted and after plug-in unit is connected to metal structure as required, also central plug can be removed at the explosive material.

The wearing face that forms can be configured to so that wearing face experiences half spontaneous layer (semi-autogenous layer) or the half spontaneous surface (semi-autogenous surface) of wearing and tearing to form broken body in fragmentation procedure.For example, the outer part that covers the wearing face of plug-in unit can experience wearing and tearing, and can lose to form half spontaneous layer from plug-in unit along with the time.Such as an example, cover plug-in unit wearing face some parts experienced wearing and tearing and be depleted from this wearing face, expose the part of plug-in unit, the part of this plug-in unit is harder than the material of covering plug-in unit.The expose portion of plug-in unit can be oriented to the adjacent part outstanding (proud) with respect to its metal structure that connects.After crushing operation or fragmentation procedure began, the expose portion of the recessed plug-in unit that exposes subsequently then formed or helps to limit half spontaneous layer of wearing face.

Broken body is preferably the roller of roller mill, vertical rolls milling train or roller press, but size can be set up and be configured to the parts as other breaker, and described other crushing device is such as being milling device, milling apparatus, disintegrating machine, pulping machine, sizer (sizer) or reducing mechanism etc.For example, broken body can be metallic plate or metallic cylinder structure, and the second metal structure 9 can be metallic plate or metallic cylinder structure.Each metallic cylinder structure can be, for example, and metal tube, metal dish, metal cylinder or metallic conduit.The metal of the metal of base portion 3a, outer part 3b and the second metal structure 9 can be 4140 grade steel.Should be appreciated that, also other steel, alloy or other metal can be used as broken body and the second metal structure to satisfy concrete purpose of design.It can also be appreciated that in some optional embodiments outer part 3b, base portion 3a also can be made of different metals with the second metal structure 9.

In other embodiments, broken body can have wearing face, and it is made of multilayer plug-in unit insert material.For example, wearing face can comprise the first base portion 23, it is connected to the first plug-in unit that comprises plug-in unit 27 and embeds metal structure 25, the second plug-in unit embeds metal structure 31, intermetallic metal structure 29 between the first plug-in unit embedding metal structure 25 and the second plug-in unit embedding metal structure 31, and the second base metal structure 33.

Should be appreciated that

metal structure

23,25,29,31 and 33 can be by each other sequentially adjacent setting, and then by the metal structure explosive welding is shaped together.For example, the first base portion 23 can be to be arranged to the cladding plate adjacent with metal structure 25 or to cover pipe, thereby at metal structure and cladding plate or cover and have the gap between the

pipe.Metal structure

29,31 and 33 can sequentially be arranged, thereby the metal structure that the gap will arrange in succession and adjacent metal structure are separated.Each gap can have different width or can have identical width.The width in each gap defines the separated isolation distance of metal structure that will be arranged on the opposition side in each gap.Certainly, some gap widths can be identical, and other can be different.Then the explosive adjacent with understructure 21 can be lighted with the metal structure explosive welding together.

Can determine that the width in gap is to meet concrete purpose of design.Should be appreciated that gap width is larger, it is larger then to be passed to the power of special metal structure from the explosive of lighting.

Alternatively, different layers can be in different blast (shot) by explosive welding together.Preferably, before the explosive welding of metal structure plug-in unit being embedded in plug-in unit embeds in the metal structure.After lighting one or more explosives, crushed element by metal structure can be connected to the plug-in unit that is embedded in each metal structure in its metal structure separately, so that crushed element engages with plug-in unit or mechanically interlock with at least a portion of the surf zone of plug-in unit.
